Application
The Metasys SNE Series of Network Engines are Ethernet-
based, supervisory devices that connect BAS networks to
IP networks. These devices monitor and control field-level
building automation devices that include HVAC, lighting,
security, and fire safety equipment.
In addition to providing general comprehensive
equipment monitoring and control, network engines also
offer specialized capabilities by series and model to meet a
variety of application requirements. The following models
are available (where x = 0, 1, or 2):
• SNE2200x-0: succeeds NAE55 Series of network
engines.
• SNE1100x-0: succeeds NAE45 Series of network
engines.
• SNE1050x-0: succeeds NAE35 Series of network
engines.
• SNE110Lx-0: succeeds NAE45-Lite Series of network
engines.
The SNE offers various integration options. Ethernet
network integrations include the following options:
• Johnson Controls and 3rd party BACnet/IP devices
- Simplex
Fire Alarm Control Unit (FACU)
®
- Molex
Lighting Control
®
- Cree
SmartCast
®
• BACnet/SC
• MQ Telemetry Transport (MQTT)
• Tyco
C•CURE
9000 or victor
®
®
• Modbus TCP/IP
• KNX IP
• OPC Unified Architecture (UA)
Field Bus integrations include the following options:
• BACnet MS/TP
• N2 Bus
• LonWorks
with USB adapter
®
• Modbus Remote Terminal Unit (RTU) with USB adapter
• Meter Bus (M-Bus)
• Zettler
Fire Panel

of all integrations available for each SNE.
Supported firmware versions
The following table lists the supported firmware versions
of Metasys Release 10.1.x and 11.0.x for the various SNE or
SNC (SNx) models. You may load an SNx with a firmware
version that is at or later than the releases listed in the
table below. For example, if you have an SNExxxx1-x at
Release 10.1.2.73, you can upgrade to Release 11.0.0.1717.
Do not load a firmware version that does not meet the
criteria in the table below.

date is also located on the shipping box label.
Installation
Follow these guidelines when installing a network engine:
• Transport the network engine in the original container
to minimize vibration and shock damage to the network
engine.
• Verify that all the parts shipped with the network
engine are present.
• Do not drop the network engine or subject it to physical
shock.
Important: Do not open the network engine
housing for any reason. The network engine has no
user-serviceable parts inside. Tamper-evident labels
on the device caution installers, service technicians,
building owners, and our RMA inspectors from
unauthorized opening or tampering of the device.
Parts included
• One SNE network engine
• One QR code SNE Pack Sheet (Part No.A163816VBR)
